A letter from Jordan to 3M in June first detailed the major problems, which included response time delays, maintenance issues and computer bugs.
The official letter of approval started a 12-month warranty period for any problems that materialize. 3M has already agreed to tweak a few minor issues.
"This acknowledges the significant improvements in system performance and stability since June," said Kansas Department of Revenue spokeswoman Jeannine Koranda. "We have achieved a number of milestones within the updated system. More than 2 million transactions have been successfully processed, and wait times returned to normal this summer."
A second phase dealing with driver's licenses is expected to launch sometime this fall, according to Koranda.
Meantime, Kansas will continue to withhold the final $2.5 million payment to 3M until the entire project is complete.
On a related note, an audit of the DMV computer implementation is expected to be finished in August, according to Deputy Legislative Post Auditor Justin Stowe.
